Question

I am making an Android application, and I have some buttons.
I want to add some listeners to them, so I have implemented android.view.View.OnClickListener, and added listeners to the buttons.

However, at the onClick method, I can’t add the Override annotation like this:

@Override
public void onClick(View view) { /* With Override */ }

But this works:

public void onClick(View view) { /* Without Override */ }

And if I try to log something in the latter onClick method, it works as intended.

I am using Eclipse, and it keeps telling me that I must override a superclass method.

Why can’t I add the Override annotation to it if I’m overriding it?

I am using Ubuntu 11.4, if that matters. java -version returns:

java version "1.6.0_24"
Java(TM) SE Runtime Environment (build 1.6.0_24-b07)
Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02, mixed mode)

Here is the code:

import android.view.View.OnClickListener;

public class Main extends Activity implements OnClickListener {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        Button btnFoo = (Button) findViewById(R.id.btnFoo);
        btnFoo.setOnClickListener(this);
    }

    // @Override
    public void onClick(View v) {
        Log.e("foo", "bar");
    }
}

PS. I’m using Sun JDK 1.6

EDIT:

I’ve found this applies to most of the methods I’m trying to use, e.g public void run() (from Runnable).
